"We know that Americans 55 and above today are relatively health conscious compared to prior generations, but it may be that the wealthiest Americans have the greatest edge in acting upon their motivations to stay healthy," said Minkler. "For instance, wealthier adults with problems walking can afford to renovate their homes to make them more accessible to wheelchairs. This could include widening doorways and installing ramps in the home's front entrance."

The researchers point out that while the rate of disability has been declining slowly but steadily over the past two decades, the aging of the baby boomer generation means that the sheer number of people with disabilities is going to increase.

"There are now almost 8,000 people turning 60 every day in the U.S.," said Minkler. "It's therefore important for us to understand all of the factors that affect disability rates. Social class is a badly neglected determinant of health and illness. This study highlights that socioeconomic status operates independently of such factors as race, ethnicity and health behaviors. Although researchers often control for social class, it warrants much more focused attention."
